Description

Technical Field

[0001] This utility model relates to the field of water quality sampler technology, specifically a real-time water quality sampling device. Background Technology

[0002] A water sampler is a device for collecting water samples. There are two types: manual water samplers and automatic water samplers. The materials used in manual water samplers must not affect the composition of the water sample and must be easy to wash, leaving no residue on previous samples. Automatic water samplers are suitable for use with a flow rate-proportional tank-type sampler. They are intelligent, multi-functional suction-type water sample dispensing devices that can achieve various sampling methods and bottling methods according to water sample sampling requirements.

[0003] Existing real-time water sampling devices typically use pumps to extract and distribute water into multiple sampling tubes to complete real-time water quality sampling. However, these devices cannot sample water at different times as needed, preventing staff from quickly sampling the same water quality at different times. This reduces the efficiency of sampling the same water quality at different times and affects the accuracy of subsequent analysis. Therefore, existing real-time water sampling devices need to be improved. Utility Model Content

[0006] A fixing frame is installed on the inner bottom wall of the box, and a bearing ring is connected to the inner wall of the fixing frame. A cylinder is installed on the inner wall of the bearing ring, and a first push rod is fixedly connected to the other end of the cylinder. An adjusting rod is slidably connected to the inner wall of the first push rod, and a second transmission rod is connected to the inner wall of the adjusting rod. An adjusting ring is fixedly connected to the outer wall of the second transmission rod, and a placement tray is fixedly connected to the outer wall of the second transmission rod.

[0007] Preferably, the take-up roller forms a rotating structure with the motor via a first transmission rod, and the extraction tube forms a take-up and release structure via the take-up roller. The other end of the extraction tube is fixedly connected to a filter head, and the filter head forms a lifting structure via the extraction tube. A filter screen is installed on the inner wall of the filter head.

[0008] Preferably, a limiting plate is installed on the inner wall of the mounting bracket, and an extraction tube is slidably connected to the inner wall of the limiting plate. The diameter of the limiting plate is smaller than the diameter of the filter head.

[0009] Preferably, the delivery tube is integrated with the extraction tube and the filter head, and the center of the delivery tube and the sampling bottle are on the same vertical line.

[0010] Preferably, the first push rod forms a telescopic structure through a cylinder, and the adjusting rod forms a rotating structure through the first push rod and the second transmission rod, with a fixed rod fixedly connected to the top of the adjusting rod.

[0011] Preferably, a bearing rod is fixedly connected to the top of the adjusting rod, and a second push rod is connected to the outer wall of the bearing rod. A return spring is fixedly connected to one side of the second push rod, and an adjusting rod is fixedly connected to the other end of the return spring.

[0012] Preferably, an adjusting ring is engaged with the outer wall of the second push rod, the adjusting ring forms a rotating structure through the second push rod, and the placement disk forms an integrated rotating structure with the adjusting ring through the second transmission rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: it is used for real-time water quality sampling devices;

[0014] 1. By using a cylinder, a second push rod, and an adjusting ring, the first push rod drives the adjusting rod to rotate along the second transmission rod. At this time, the adjusting rod and the bearing rod drive the second push rod to slide along the adjusting ring. When the second push rod slides to the push groove of the adjusting ring, the second push rod pushes the adjusting ring to rotate through the subsequent angle adjustment of the adjusting rod. This solves the problem that existing real-time water quality sampling devices cannot sample water quality at the same depth at different times according to needs. This makes it easier for staff to quickly sample the same water quality at different times, improves the efficiency of staff to sample the same water quality at different times, and ensures the accuracy of subsequent analysis of the same water quality at different times.

[0015] 2. The system utilizes a motor, a take-up roller, and an extraction tube. The motor drives the first transmission rod and the take-up roller to rotate, while the take-up roller adjusts the opening and closing of the extraction tube. This allows the extraction tube to bring the filter head into contact with water at different depths, enabling real-time sampling of water at various depths. This facilitates sampling at different depths and improves the efficiency of the sampling process. Furthermore, a filter screen is installed on the inner wall of the filter head to prevent blockage during water transport through the extraction tube, ensuring the stability of the real-time water sampling device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a real-time water quality sampling device, including a box 1, a sealing cover 2 installed on the top of the box 1, and a control panel 3 provided on the top of the sealing cover 2. A mounting frame 4 is installed on the outer wall of the sealing cover 2, and a motor 5 is provided on the outer wall of the mounting frame 4. The output shaft of the motor 5 is connected to a first transmission rod 6 through a coupling, and a winding roller 7 is fixedly connected to the outer wall of the first transmission rod 6. An extraction tube 10 is slidably connected to the outer wall of the winding roller 7, and a conveying tube 11 is fixedly connected to one end of the extraction tube 10.

[0024] The take-up roller 7 forms a rotating structure with the motor 5 through the first transmission rod 6, and the extraction tube 10 forms a take-up and release structure through the take-up roller 7. The other end of the extraction tube 10 is fixedly connected to the filter head 8, and the filter head 8 forms a lifting structure through the extraction tube 10. The inner wall of the filter head 8 is equipped with a filter screen.

[0025] The inner wall of the mounting bracket 4 is fitted with a limiting plate 9, and the inner wall of the limiting plate 9 is slidably connected with an extraction tube 10. The diameter of the limiting plate 9 is smaller than the diameter of the filter head 8.

[0026] The delivery tube 11 is integrated with the extraction tube 10 and the filter head 8, and the center of the delivery tube 11 and the sampling bottle 24 are on the same vertical line.

[0027] The specific implementation method is as follows: Through the motor 5, the take-up roller 7 and the extraction tube 10, the motor 5 drives the first transmission rod 6 and the take-up roller 7 to rotate. At this time, the take-up roller 7 adjusts the take-up and unwinding of the extraction tube 10 so that the extraction tube 10 drives the filter head 8 to contact the water quality at different depths, thereby completing the real-time sampling of water quality at different depths. This facilitates the sampling of water quality at different depths by the staff and improves the efficiency of the sampling of water quality at different depths. At the same time, the inner wall of the filter head 8 is equipped with a filter screen, which prevents the water quality from being blocked during the transportation of the extraction tube 10 and ensures the stability of the real-time water quality sampling device.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a real-time water quality sampling device, wherein a fixing frame 12 is installed on the inner bottom wall of the housing 1, and a bearing ring 13 is connected to the inner wall of the fixing frame 12. A cylinder 14 is installed on the inner wall of the bearing ring 13, and a first push rod 15 is fixedly connected to the other end of the cylinder 14. An adjusting rod 16 is slidably connected to the inner wall of the first push rod 15, and a second transmission rod 17 is connected to the inner wall of the adjusting rod 16. An adjusting ring 22 is fixedly connected to the outer wall of the second transmission rod 17, and a placement plate 23 is fixedly connected to the outer wall of the second transmission rod 17. A sampling bottle 24 is installed on the inner bottom wall of the placement plate 23, and a limiting plate 25 is engaged with the outer wall of the sampling bottle 24.

[0029] The first push rod 15 forms a telescopic structure through the cylinder 14, and the adjusting rod 16 forms a rotating structure through the first push rod 15 and the second transmission rod 17. The top of the adjusting rod 16 is fixedly connected to the fixing rod 18.

[0030] The top of the adjusting rod 16 is fixedly connected to the bearing rod 19, and the outer wall of the bearing rod 19 is connected to the second push rod 20. One side of the second push rod 20 is fixedly connected to the return spring 21, and the other end of the return spring 21 is fixedly connected to the adjusting rod 16. The return spring 21 forms a compression structure with the fixed rod 18 through the second push rod 20.

[0031] The outer wall of the second push rod 20 is engaged with the adjusting ring 22. The adjusting ring 22 forms a rotating structure through the second push rod 20, and the placement plate 23 forms an integrated rotating structure with the adjusting ring 22 through the second transmission rod 17.

[0032] The specific implementation method is as follows: Using the cylinder 14, the second push rod 20, and the adjusting ring 22, the first push rod 15 drives the adjusting rod 16 to rotate along the second transmission rod 17. At this time, the adjusting rod 16 and the bearing rod 19 drive the second push rod 20 to slide along the adjusting ring 22. When the second push rod 20 slides into the push groove of the adjusting ring 22, it pushes the adjusting ring 22 to rotate through the subsequent angle adjustment of the adjusting rod 16. This solves the problem that existing real-time water quality sampling devices cannot sample water quality at the same depth at different times according to requirements. This facilitates rapid sampling of the same water quality at different times by staff, improves the efficiency of sampling the same water quality at different times, and ensures the accuracy of subsequent analysis of the same water quality at different times.

[0033] Working principle: When using this water quality real-time sampling device, firstly, by driving the sealing cap 2, the sampling bottle 24 required for sampling is inserted into the placement tray 23 through the limiting plate 25. At this time, the motor 5 set on the outer wall of the mounting frame 4 is started by the control panel 3, so that the motor 5 drives the first transmission rod 6 to rotate, thereby driving the winding roller 7 to rotate, and then driving the extraction tube 10 to adjust the winding and unwinding through the winding roller 7.

[0034] At this time, the extraction tube 10 drives the filter head 8 fixed at the other end to move up and down synchronously, so that the control panel 3 passes through the filter head 8 to the extraction tube 10, thereby obtaining the sampling depth of the extraction tube 10 through the control panel 3, and then extracting water quality through the control panel 3 and the filter head 8. At this time, the delivery tube 11 extracts water quality through the extraction tube 10 and the filter head 8, so that the delivery tube 11 delivers water quality into the sampling bottle 24, completing the sampling of water quality at different depths.

[0035] When staff need to obtain water quality data at the same depth at different times, cylinder 14 is activated to extend and retract push rod 15, which in turn pushes adjustment rod 16. Simultaneously, cylinder 14 rotates along fixed frame 12 via bearing ring 13, ensuring the stability of push rod 15's push on adjustment rod 16. Adjustment rod 16 then rotates along transmission rod 17, causing fixed rod 18 and bearing rod 19 to adjust synchronously. This, in turn, push rod 20 slides along adjustment ring 22 via adjustment rod 16 and bearing rod 19. Since the outer wall of push rod 20 is irregularly shaped, push rod 20, through adjustment ring 22, compresses return spring 21 in conjunction with adjustment rod 16.

[0036] When the second push rod 20 slides into the groove of the adjusting ring 22, the return spring 21 restores its deformation and drives the second push rod 20 to engage with the groove of the adjusting ring 22. This allows the second push rod 20 to push the adjusting ring 22 to rotate through the subsequent rotation of the adjusting rod 16. As a result, the adjusting ring 22 drives the second transmission rod 17 to rotate, which in turn drives the placement plate 23 and the limiting plate 25 to rotate synchronously. This completes the adjustment of the sampling bottle 24 installed on the bottom wall of the placement plate 23, making it easier for staff to adjust the sampling bottle 24 and improving the efficiency of water quality sampling at the same depth at different times.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
